Human Intestinal Spirochetosis Shows Higher Positivity in Sessile Serrated Lesions Than in Tubular Adenomas With Preferential Colonization of Absorptive Epithelium. [PDF]

Pathol Int
Human intestinal spirochetosis (HIS) positivity was significantly higher in sessile serrated lesions (SSLs) than in tubular adenomas (TAs). HIS preferentially colonized absorptive epithelium, which is abundant in SSLs but limited in TAs, indicating that differences in absorptive epithelial abundance account for the higher HIS positivity in SSLs ...

Periodontal microbiology and microbial etiology of periodontal diseases: Historical concepts and contemporary perspectives

Periodontology 2000, EarlyView., 2023
Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

Europe's contribution to the evaluation of the use of systemic antimicrobials in the treatment of periodontitis

Periodontology 2000, EarlyView., 2023
Abstract This narrative review celebrates Europe's contribution to the current knowledge on systemically administered antimicrobials in periodontal treatment. Periodontitis is the most frequent chronic noncommunicable human disease. It is caused by dysbiotic bacterial biofilms and is commonly treated with subgingival instrumentation.

The natural history of periodontal disease: The Java study—Origin, implementation, and results 35 years on

Periodontology 2000, EarlyView., 2023
Abstract This review describes the origin and results of the prospective longitudinal study to test potential prognostic indicators for periodontal breakdown in a population deprived of regular dental care. Experimental gingivitis studies in individuals highly susceptible or highly resistant to periodontitis showed that bleeding on probing developed ...

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

Biophysical and Biochemical Characterization of TP0037, a d-Lactate Dehydrogenase, Supports an Acetogenic Energy Conservation Pathway in Treponema pallidum

mBio, 2020
A longstanding conundrum in Treponema pallidum biology concerns how the spirochete generates sufficient energy to fulfill its complex pathogenesis processes during human syphilitic infection.

Culture and identification of Borrelia spirochetes in human vaginal and seminal secretions [version 3; referees: 2 approved, 2 not approved]

F1000Research, 2015
Background: Recent reports indicate that more than 300,000 cases of Lyme disease are diagnosed yearly in the USA. Preliminary clinical, epidemiological and immunological studies suggest that infection with the Lyme disease spirochete Borrelia burgdorferi

The association between gingivitis and oral spirochetes in young cats and dogs.

PLoS ONE, 2023
Although gingivitis frequently occurs in young cats, spirochetes are often found in the early stages of periodontal disease. This study was conducted to determine the association between gingivitis and oral spirochetes in young cats and dogs.
